Total Recall

In 2084, Mars is a colonized world under the tyrannical regime of Vilos Cohaagen, who controls the mining of valuable turbinium ore. Construction worker Douglas Quaid experiences recurring dreams about Mars and a mysterious woman, leading him to visit Rekall, a company that implants realistic false memories, where he chooses one on Mars as a Martian secret agent. However, before the implant is completed, he lashes out, already thinking he is a secret agent. Believing Cohaagen's "Agency" has suppressed Quaid's memories, the Rekall employees erase evidence of his visit and send him home.
